Mei Momozono  

, 桃園 メイ

A woman with extensive knowledge in computer science and physics teaches math at the university's physics department. From childhood, she was trained to serve Sorata but decided not to blindly follow him until she saw him herself. If required, she would even sacrifice her life for respect. During a mission, she chose to follow Sorata despite her insistence that he leave her alone. Her grandfather is the chairman of the school, although it's owned by the Muon family. She appears to be a shotacon and gets turned on when seeing Sorata in shorts (Steals 4 and 5).
